What temperature should the refrigerator and freezer be set for? Which part of the dial is the indicator i.e. which should be pointing to the number desired, the smooth or the rough part of the dial. Can't find manual. Refrigerator was freezing veggies, hubby changed setting without resource so don't remember details from the manual on where it should be set. Currently testing with (outdoor) thermometer and freezer is running 8 to 10 degrees. Don't think that is cold enough but not sure.
